Preparing The Projector For Operation - Mitsubishi Electric XD300U User Manual

Preparing the projector for operation

Getting ready for projection
1. Connect the power cord provided to the projector.
2. Connect the power cord to the wall power outlet.
3. Remove the lens cap.
Warning:
• Do not look directly into the lens when projector is
"ON".
• The lens cap is for protecting the lens. If you leave
the power on with the cap on, the cap may be warped.
Please remove the lens cap when you turn the power
on.
• This projector is equipped with the power cords for
both U.S. and Europe. Use the appropriate power
cord for your country.
• A three-pin grounding type power plug is used with
the projector. Do not remove the grounding pin on
the power plug. If you are unable to insert the plug
into the outlet, contact your electrician to replace
your A/C outlet.
• The supplied power cord for U.S. is used for 120V
only. Never connect to any outlet or power supply
having a different voltage or frequency. If you
connect to the power supply having a different
voltage, please use the appropriate power cord.
• Use 100-240V AC 50/60Hz correct voltage other-
wise it may lead to fire or electric shock.
• Do not place any objects on the power cord, and keep
the projector away from heat sources to avoid break-
ing the power cord. A broken power cord can cause
fire or electric shock.
• Do not revise or alter the power cord otherwise it
may cause fire or electric shock.
Contact your dealer if the cord is broken.
Caution:
• Plug in firmly and unplug by holding the plug, not
by pulling the cable out.
• Do not plug in or out with wet hands. It may cause
an electric shock.
Adjusting the angle of projection
For the best result, project onto a flat screen with a 90
degree angle to the floor. If necessary, tilt the projector
by adjusting the adjustment feet on the bottom of the
projector.

Front adjustment feet
1. Lift the projector to an appropriate angle.
2. Press the foot adjustment buttons, and the front
adjustment feet will slide out to their appropriate
positions.
3. Release the foot adjustment buttons to fix the feet
in those positions.
4. Turn the feet for fine adjustment.
• The projection angle can be adjusted by turning
the rear adjustment feet.

5. Put the front adjustment feet back into the projector.
• Install the screen on a flat wall at 90 degrees to
the floor.
• Position the projector so that it projects an image
filling the screen as illustrated on page 9.
• Keep an appropriate distance from the projector
to the screen according to the screen size chart on
page 9.
• The image distorts to be trapezoidal in shape as
the screen or projector is tilted. Use KEYSTONE
button and $, %, { or } buttons to correct the
distortion. Due to this correction, however, the
circumference of the image may become out of
focus.
• The projector shall be installed at a tilting angle
within 15 degrees, but the keystone adjustment
angle can be set exceeding 15 degrees.
Important:
• Noise may appear on the screen during the
keystone adjustment depending on the type of
video signal being projected. This is not a failure.
In such a case, reduce the keystone correction
value to eliminate the noise.
• You can correct the vertical and horizontal
keystones at the same time. In such a case, the
upper limits of the correction values for the
vertical and horizontal keystones vary as their
adjustable ranges change in relation to each other.
• The image may not be projected in a shape of a
regular rectangle or with its aspect ratio of 4:3,
depending on the installation conditions of the
projector and the screen.
• When the keystone adjustment is carried out, the
adjustment value is indicated. Note that this
value doesn't mean a projection angle.
• The allowable range of the adjustment value in
the keystone adjustment will vary depending on
the installation conditions.
• When the keystone adjustment takes effect, the
resolution decreases, and strips appear or straight
lines bend in images with complicated patterns.
They are not due to a failure of the projector.
